Since 1950 to 2018, about 6.3 billion tonnes of plastics have been produced worldwide, 9% and 12% of which have been recycled and incinerated, respectively. Human population increase and consistent demand for plastics and plastic products are responsible for continuous increase in the production of plastics, generation of plastic waste and its accompanied environmental pollution. We have reviewed in this paper, the most relevant literatures on the different types of plastics in production, the h...

The systemic toxic effects of di-isononyl phthalate (DINP) were evaluated in a 4-wk study in male Sprague-Dawley rats. The animals were administered DINP intravenously at dosages of 125, 250, and 500 mg/kg every other day for 4 wk. The control and the positive control group were administered vehicle (egg yolk phosphatides plus glycerol solutions) and 500 mg/kg di(2-ethylhexyl) phthalate (DEHP), respectively. Clinical signs were observed immediate...

Pharmaceuticals are the most common medical intervention. Ensuring workers and members of the public get the most benefits from advances in modern medicine is a critical component of improving the health care system. Pharmaceuticals bring healing to patients but increased risk of illness have been reported among workers manufacturing, handling and administering pharmaceutical products with inadequate attention to personal safety. Their potential for both helping and harming human health can be p...

The contamination of heavy metals in soil was assessed with single-factor pollution index method and Nemerow comprehensive pollution index method. The results showed that Cu, Cr, Ni, Pb, Co were main risk factors of soil heavy metal pollution. In Gulin,...

Bisphenol A (BPA) is being considered by the European Union as a substance of very high concern, occurring worldwide due to its wide application in many plastic products, building materials, coatings and epoxy resins. The toxicity of BPA in groundwater invertebrates is insufficiently understood. Both acute (24 h) and chronic (28 d) toxicity was compared in Daphnia magna and ecologically important crustaceans in surface water (Gammarus fossarum, E...

In this paper we discuss the problem of predicting the fish toxicity property of chemical compounds, and show how this can be approached using a computational intelligence method. There are two views on assessing toxicities: One says that such properties can be derived from the whole molecular structure, the other that some specific functional substructures, called Structural Alerts (SA), are able to explain the toxicity. In this work, a new Structure-Activity Relationship (SAR) approach is prop...

Heavy metals and metalloids, some of which are extremely beneficial for the survival of humans, flora and fauna can have devastating effects on same and the environment. Bioaccumulation and bio-magnification two methods via which metals and metalloids are assimilated into food chains as well as dermal and ingestion exposure to heavy metals and metalloids are believed by many residents in the Obuasi Municipality as leading public health threats to peasant farmers, their spouses and children. Risk...

Many health-conscious consumers are increasingly making deliberate choices for plant-based diets because probably they think they were safer. Majority of these consumers who dwell in cities therefore demand leafy vegetables for their daily consumption. The demand has created the opportunity for many urban dwellers to join the business of vegetable cultivation using every space available. Urbanization is associated with industrialization, and with it comes the attendant anthropogenic hazards. Sub...

All pesticides are potentially toxic to all sorts of life and some are even classified as probable human carcinogens, neutrotoxics and endocrine system disruptors. The toxicity level of a pesticide depends on the lethal dose (LD) of the chemical, the length of exposure, and the route of entry or absorption by the body. There are many different pesticides in use today with very different modes of action and levels of toxicity. To protect the public, WHO has developed a hazard classification syste...

Ecological risk assessments (ERAs) for contaminated terrestrial sites regularly include mammals as receptors-of-concern whose home ranges dwarf the sites by tens of times. As a consequence, opportunities to sustain chemical exposures of concern are greatly limited. In having notably miniscule densities as well, wide-ranging mammals are poorly selected species to evaluate because true populations are effectively non-existent at sites. Collectively...

Heavy metals emission, in particular, mercury is ever increasing due to global urbanization and industrialization. Due to increasing number of health problems related to heavy metals contamination, monitoring it becomes a crucial task for authorities and environmentalists. Therefore, the development of a nanobiosensing technique that can detect mercury ions as low as 1 ppb for its limit of quantification is necessary to provide sufficient informa...

Lead is a widespread toxicant with well-established detrimental health effects. Environmental exposure to lead occurs through different means such as industrial and combustion sources, lead paint, folk remedies, glazed pottery, and sometimes by drinking water. Some groups are disproportionately exposed to lead, including those who live close to industrial facilities or with low socio economic status and workers in small or mobile workplaces such ...

Exposure to polycyclic aromatic hydrocarbons (PAHs) is associated with possible carcinogenicity, according to European directives. Studies helped to clarify the contributions to the total dose resulting from environmental and occupational exposure, by tobacco smoke, by diet and skin absorption. Recently, it was shown that levels of 1-Hydroxypyrene U (1-OHPu) may be predictive of individual dose, environmental and employment exposure, proportionat...

Even though the adverse effects on environment and organism health have been long and thoroughly studied, the problem represented by the continuous use of neurotoxic pesticides, in particular organophosphates (OPs, organic salts of the pyro phosphoric acid), is still open. These are considered as emerging pollutants, as their massive employment is relatively recent, dating after the ban of persistent organic pesticides. OPs are not persistent for...
